I connnnsarron DRAIN nnvrcn.

Application filed April 13, 1925. Serial lilo. 22,825.

To all 1072 om it may concern:

Be it known that I, HARVEY L. BULLooK, a citizen of the United States, and a resident of North White Plains, in the county of Westchester'and State of New York, have invented a new and Improved Condensation Drain Device of which the following is a,

full, clear, and exact description.

This invention relates to condensation drain devices and more particularly to an automatically controlled. valve mechanism condenses in an apparatus is ejected in" spurts whenever the governorblows off and:

which also blows when the pressure in the tank falls to a predetermined degree.

With these and other objects in view, the.

invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view in longitudinal section illustrating my improved device;

Figure 2 is a view in transverse section on the line 22 of Figure 1. I

Figure 3 shows diagrammatically an air brake system with my invention applied thereto.

1 represents a metal block having a longitudinal bore 2 in its upper portion, the wall of this bore being screw-threaded for the reception of a threaded nipple 3 on a-tubular coupling 4, the latter having an angular wrench-receiving portion 5.

The lower portion of the block 1 is formed with a bore 6 which is concentric with the bore 2 but smaller in diameter than the bore 2. A valve seat 7 is formed internally of the block 1 at the point of juncture between the longitudinal bores 2 and 6.

The lower end of the wall bore 6 is screwthreaded to receive a cylindrical externally screw-threaded tube 8', the latter having a knurled lower'end 9'and a lock nut 10 thereon which is jammed against the block 1 to secure the tube 8 at the desired adjustment.

A coil spring 11 is seated on the upper end of the tube 8 in the bore 6. and exerts pressure against a ball valve 12, the latter normally seated against the seat 7 by reason of the air pressure in the tank (not shown) to which connected.

The block 1 is made with a screw-threaded socket 13 in one side into which a threaded nipple 14 on a tubular arm 15 is ti htly screwed. This arm 15 at its outer on has a longitudinal bore 16 constituting a cylinder in which a piston 17 is movable. An angular plug tap 18 is screwed into the outer end of the arm 15 and'has a projection 19 thereonconstitutin a piston stop.

the pipe or coupling'4is The piston 174's provided with a cup washer 5 20 secured in place by a disk 21 and a screw 22's0 as to prevent leakage around the piston.

A rod 23 is fixed to the piston 17, prefer-- ably, by screwing one end of the rod into a recess in the piston as shown at'24. The

rod 23 is of appreciably less diameter than that portion 25 of the bore of arm 15 in which it is movable, and the free end of said rod is adapted to engage a ball valve 26" normally located against a seat 27.

The valve 26 is movable in a cylindrical chamber 28 between the seat 27 and a seat 29 on a sleeve 30 which fits the chamber. 28. A port 31 connects the bore 2 with chamber 28 and a gasket 31 is located between the sleeve 30 and the block 1 to insure an airtight juncture of the parts. A water discharge orifice 32 is-for'med in the arm 15 and communicates with the reduced bore 25 back of valve 26. Q

The operation of my improved device is as follows:

As shown diagrammatically, in Figure 3' the pipe or coupling 4 is connected with the air tank 40 andreceives therein by gravity water which condenses in the tank. The plug tap 18 is connected to an electric governor 41 by means of pipes 42 and 43. The

7 main reservoir 40. All of the parts just described constitute standard equipment "of an air brake system and my automatic condensation drain device is shown attached with block 1 it will flow through the port'31 into the chamber. 28. Whenever the governor blows 01f, the pressure will be; 'sufli" cient to 'move' the piston 17 an% rod 23 to the left of Figure 1, moving the all valve 26 from seat 27 to seat 29. When the pressure from the-governor is reduced, the ball valve 26 will move back to the seat 27 and invention and hence I do not limit eject a small amount of water-through the o ening 32;- As this operation of moving tl ie ball val-ve by the governor is frequent this operation serves to eject the condensation in spurts and prevents the' over-accu- 'mulation of water. When the pt'essure in the tank diminishes to a certain degree the spring 11 will force the ball valvex 12 from its seat 7 and allow the water'to flow down through the tube 8 and escape.

Various slight changes and alterations might be madein the general formof the parts described without departing from my myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the'spirit andscope of the appended claims. I claim: J 1. A device of the character described, including a cylinder, a piston in the cylinder operated by an air governor, a water accumulating chamber adapted to communicate with an air-tank, a valve in said chamher having two seats spaced apart, and said valve moved from one seat tothe "other by the action of the piston.;and said device having a drain orifice back of the valve throu h which the water escapes.

cluding a block having a valve chamber last-mentioned va one seat to another, and said arm having' an escape orifice back of the last-mentioned therein adapted to be connected to an air tank, a ball valve normally seated 'in the lower !portion of said valve chamber, a tubular adjusting member in the block, a spring interposed between said member and the ball valve, a tubular arnrfixed to the block and communicating with said valve chamber, said. arm having a valve chamber therein with valve seats spaced apart, and a ball in saidlast-mentioned valve chamber movable from one seat to another, and saidarm having an escape orifice-back of the lastmentioned ball valve.

4. A device of the character described, in cluding a block having a valve chamber therein adapted to be connected to an air tank, a ball valve normally seated in the lower portion of said valve member, a tubular ad usting member in the block, a spring interposed between said member and the ball valve, a tubular arm fixed to the block and communicatin with said valve chamber, said arm having a valve chamber therein with valve seats spaced apart, a ball in said ve chamber movable from ball valve, a piston movable in thearm, a

rod on the piston adapted to engage the.

last-mentioned ball valve and move itfrom one seat to the other, and a lug tapjn the end of the arm adapted to connected to an air governor. Y

5. A device ofthe character described, including a pair of ball valves having water escape openings back of the same, a spring exerting pressure on one valve, and a piston adapted to move one valve and op 2. devlce of the character described, in-' erated by'air pressure.
